Described as "Changing Lanes on Wall Street," Rule Number Three would "star De Niro as an everyday schlub determined to take down an arrogant Wall Streeter played by Hugh Grant. Grant's character has been described to (Fox 411) as the kind of guy from Enron, Tyco or ImClone who lives high on the hog while bilking his investors."

De Niro's next release, Analyze That, opens Friday. His other future projects include The Good Shepherd and Meet the Fockers. Hugh Grant will appear in Love Actually and Two Weeks Notice.
